4 Claims. 1

This invention relates to a combined ventilator and screen, attachable to windows and adapted to control the air flow into the room and at the same time exclude rain, snow and insects.

An object of this invention'is the provision in a ventilator of the character described, of a frame which may be secured to a window sash and which carries a series of closely spaced louvers, and a covering panel detachably mounted upon the said frame and adjustable thereon to regulate the flow of air into a room.

Another object of this invention is the particular arrangement of the louvers to permit the entrance of air into the room while at the same time excluding the admission of rain, snow and insects, while keeping the window locked.

A further object of this invention is the inclu sion therein of transparent louvers and closure panel which are constructed and arranged to permit outside light to enter the room at all times.

A still further object of this invention is the provision of an organization in which the constituent elements are so arranged structurally and functionally as to assure improved results with materials and members which may be manufactured at reasonable cost, may be easily assembled and which will be efiicient in operation with minimum wear to the parts.

This invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description and in the claims wherein parts will be identified by specific names for convenience, but they are intended to be as generic in their application to smiliar parts as the art will permit. In the accompanying drawings there has been illustrated the best embodiment of the invention known to me, but such embodiment is to be regarded as typical only of many possible embodiments, and the invention is not to be limited thereto.

The novel features considered characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a, specific embodiment when read in connection with the accompanying drawings, in which:

Figure 1 is a perspective view of the ventilator minus the closin and regulating panel.

Figure 2 is an end elevational view, partly in section, of the ventilator and shows the closing and regulating panel attached.

2 Figure 3 is a sectional plan view of the ventilator and shows a fragment of a window casing and sash to which the ventilator is attached.

Figure 4 is an isometric view of the regulating and closing panel.

Figure 5 is an enlarged fragmentary detail, which will be hereinafter described.

Figure 6 is a detail showing a means for locking the closing and regulatin panel in a fixed position, and

Figure 7 is a front elevational view showing the device attached within a window sash.

Referring in detail to the parts, ll designates a frame having upper and lower supporting brackets 12 and I3 respectively, over which a regulating and closing panel I4 is adapted to be suspended. Slots I5 and I6 are formed in the said closing and regulating panel M, which are adapted to engage over the said brackets l2 and I3 respectively, to hold the said panel in place.

The frame II is provided with closely spaced and very thin louvers l1, arranged to form very narrow slotted openings I8, best illustrated in Figure 5. The said frame Il may be mounted directly upon a window sash [9, as shown in Figure 3, or within a cutout portion of the glass pane 20, shown in Figures 2 and '1.

In the form shown in Figure 3, the frame may be attached to the sash by ordinary screws engaging through perforations 2l (see Figure 1). and into the sash l9. In the form shown in Figures 2 and 7, where attachment is made to the glass 20, a clip (see Figure 2), having an outside member 22 and an attached inside clamping member 23, forms an inner groove 24, to re ceive the frame II, and an outer groove 25, to hold the said frame ll within the cutout portion of the glass pane 20. The outside member 22 and the inside clamping plate 23 (Fig. 2) are adapted to form a holding frame which extends around the frame H and inside of the cut-out portion of the pane 20, with the tongue and groove joint 24 adapted to hold the said holding frame upon the pane 20 and in turn hold the frame II in place.

The aforesaid upper brackets l2 are formed with inner and outer notches 26 and 2'! respectively, and the lower brackets l3 are formed with inner and outer notches 28 and 29 respectively, within which the said panel l4 engages.

When the ventilator is mounted within a cutout portion of the window pane or upon the sash without the said regulating and closing panel, a maximum amount of outside air may enter the room through the openings l8, between the M, as indicated by the arrows in Figure 2. The I admission of air, however, may be entirely shut ofi by moving and suspending the said closing and regulating panel M, in the notches "ZS and- 2-8; upon the brackets 62 and [3 respectively, as shown in Figure 3.

A locking clip 30, which may be rotatably attached to the frame H, and which may engage through a slot 3| in the said closing and regulating panel iS'DIOVidEdLaS'B, means to prevent the displacement of the 'said' closingand regulating'panel l4.

' The entire device, including the'frame carrying the louvers and the closing and regulating'panel, is preferably made of transparent plastic or of any other suitable transparent material.

Obviously, the device may be varied in size to fit either a partof'awindowsash or a part of a complete window, or it may be made large enough to fit the entire'window opening.

I claim:

'1.- A ventilator comprising a frame secured to a 'window sash, the glass pane of which is removed or partly cut away, a series of closely spaced rality of notches to adjustably hold the said louvers in said frame, upper and lower brackets upon said frame, and a panel member having upper and lower perforations therein adapted to engage over the said upper and lower brackets.

2. A ventilator as defined in claim 1, in which the said cut away portion of the said pane is rimmed by a cli member adapted to secure and hold the said frame carrying said louvers' in position upon and within the said out out portion of the said pane 3. The device as set forth in claim 1, wherein the said louvers and said closing and regulating panel :are made of transparent material.

4. The device as set forth in claim 1, wherein the supporting brackets are provided with a pluclosing and regulating panel.
